Question

Assume the distance above the ground is represented by positive integers
and that below the ground by negative integers.

Answer 1

Answer:

Step-by-step explanation:

(i) Displacement = Velocity x Time = -5 m/min x 60 min = -300 m.

(ii) Displacement from initial position = Velocity x Time = -5 m/min x 45 min = -225 m.

However, since we started 15 m above ground, displacement from the ground level = -225 + 15 m = -210 m.
